JAMES W. KOCH, OF TAMAQUA, PENNSYLVANIA.

COMBINED NUT-LOCK AND ANTIRATTLER.

Specification of Letters Patent.

Patented Feb. 4, 1 908.

Application filed July 23. 1907. Serial No. 385.116.

T 0 all whom it may concern:

Be it known that I, JAMES W. Koo-n, a citizen of the United States,residing at Tamaqua, in the county of Schuylkill and State ofPennsylvania, have invented certain new and useful Improvements in aCombined Nut-Lock and Antirattler, of which the following is aspecification.

My invention relates to combined nut locks and antirattlers, and has forits primary object to provide a novel construction of the same embodyinga wedge having a removable weight thereon that acts also as a lock forthe nut.

My invention also embodies certain other novel features, as will behereinafter pointed out and claimed, reference being had to theaccompanying drawing, in which Figure 1 is a perspective view of myimproved construction, the key being removed from position, and thewasher being shown detached. Fig. 2 is a vertical sectional view of thesame. Fig. 3 is a detail perspective view of the wedge plate. Fig. 4 isa detail sectional view of the end of the bolt. Fig. 5 is an enlargedperspective view of a modified form of the key.

Similar numerals of reference denote corresponding parts in the severalviews.

In the said drawing the reference numerals 1 and 2 denote the twomembers to be connected, and 3 the threaded bolt connecting the same,said bolt having the headed end 1 and preferably an enlarged angularportion 5 adjacent said head to prevent said bolt from turning.

With the parts in position there is located on said bolt next to member2, a wedge plate 6, apertured longitudinally at 7 to receive the boltend and yet permit a vertical adustment of said wedge plate thereon.Contacting with said wedge plate is a nut 8 screwed onto the bolt 3, asshown. Formed on the lower end of said wedge plate 6 is a horizontallydisposed key-way 9, adapted to receive a locking piece or weight 10 thatis slotted on one face to correspond with said key-way. With the wedgeplate and nut in position, the locking piece or weight is slid onto thekeyway 9 until its upper inclined face 11 contacts with the lower faceof nut 8 and wedges thereagainst, said locking iece or weight thusperforming the two-fold function of a lock for said nut, and of a weightfor said wedge-plate to retain the latter in position. In order toprevent the accidental withdrawal of said locking piece or weight Iprovide a spring-ring 12, which is passed through an aperture 13 in thewedgeplate, and locks said locking piece or weight in position.

vv hen it is desired. to employ a washer 1 1 on said bolt I lock thesame in position by means of a key 15 having a circular body portion, ahead 16 and a broadened but tapered point 17, which will pass through asimilarly shaped aperture 18 in the bolt 3 and which may then be turnedto have its head and point he flat against said washer, as shown in Fig.2. To insert said key, it is necessary to first move the wedge plate toits upward limit of movement and screw nut 8 further in, to give roomfor the point 17 of key 15 to enter aperture 18 in bolt 3 lengthise.Then when the key 15 is turned to the position shown in Fig. 2, the nut3 may be screwed out again to force washer 14 against key 15, the wedgeplate 6 forced down, and the locking piece or weight 10 inserted inposition, the whole combining to provide a securely locked device thatwill also serve as an anti-rattler, the weighted wedge plate 6automatically accommodating itself to the space between member 2 and nut8.

If desired I may connect spring ring 12 and key 15 by means of a chain19 and may provide in the end of key-way 9 opposite the aperture 13 aslot 20 shaped to receive and retain the point 17 of key 15 when thesame is not in use w ith a washer 14.

My improved, device is particularly applicable to use where the membersto be held together are subject to jars, such as vehicles of varioussorts, the weighted wedge plate accommodating itself automatically tovariations in the space between member 2 and nut 8.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is

1. In combination, a threaded bolt, a nut thereon, a verticallyadjustable apertured wedge plate between said bolt and the part throughwhich said bolt passes, and a weight removably mounted on said wedgeplate and adapted when positioned to contact with and lock said nutagainst rotation.

2. In combination, a threaded bolt, a nut thereon, a verticallyadjustable apertured wedge plate between said nut and the part faceadjacent to said nut angularly disposed 1 key having enlarged endsassing through an to engage and Wedge against said nut. aperture in saidbolt and ocked thereon by 3.
